**2.12 Other diets**

Based on the knowledge about the effects of different macronutrients on circulating glucose levels many other popular diets have been introduced. These diets have not been studied using controlled trials so the outcomes are not authenticated. These diets include the Paleo diet, Atkins diet/keto diet, Nutrisystems etc. They are all focused on weight loss. It is important to account for the different macro and micronutrients on maintaining normal metabolism in the body. Therefore, a carbohydrate free or a fat free diet or vegan diet can be very deleterious to health, unless there is a balance in the nutrient intake.
